摘　　要：现有高压开关柜温度在线监测系统存在安装维护复杂、传感器供电不可靠、接口开放性差等不足。针对该问题,基于面向过程控制的OLE技术(OPC),设计一种新的温度监测系统。利用无源无线的声表面波温度传感器采集温度信息,通过ZigBee无线网络进行数据传输,实现高压开关柜温度在线监测与集中显示,同时采用OPC服务器软件架构屏蔽设备的底层私有协议,便于与其他测控平台实现无缝集成。实验结果表明,该系统能够克服协议私有、接口不开放的弊端,具有较好的工程应用价值。High voltage switchgear temperature online monitoring system currently exists mostly presence deficiencies of complexity for installation and maintenance,unreliable sensor power supply and private interface. In view of this problem,this paper designs a new temperature monitoring system based on Object Linking and Embedding for Process Control（ OPC） technology which achieves online monitoring and centralized display switchgear temperature information by using Surface Acoustic Wave（ SAW） temperature sensor and ZigBee wireless network to transfer temperature information. And software architecture of OPC serveris used which shields private protocol at the bottom of the device to facilitate the realization of seamlessly integrated with other measurement and control platform. Experimental results show that the designed system can overcome the disadvantages of private protocol and not open interface,and has good engineering application value.
